The PLC program control is adopted, and the full-automatic operation with timing and constant pressure difference is realized; the filtered clean water in the system is utilized to back flush the filter layer, so that an additional back flush water pump is not needed, and the energy consumption is saved; the single tank has small volume, light weight, simple operation, convenient maintenance, low investment and high efficiency; the electric three-way ball valve is used as a reversing valve, so that the operation is reliable and the service life is long.
Description
Technical Field
The utility model relates to a combination formula shallow sand filter.
Background
The existing high-speed filter, multi-medium filter, mechanical filter and the like have large occupied area and are inconvenient to use and maintain; the traditional shallow sand filter adopts a hydraulic control valve, and sometimes the valve action is not in place, so that the normal operation of backwashing is influenced.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model discloses a modular shallow sand filter.
The technical scheme of the utility model is that: modular shallow sand filter, including a plurality of horizontal jar of body, horizontal jar of body one side is equipped with visual manhole, and the through connection has the inlet tube on the horizontal jar of body, and inlet tube one side intercommunication has the blow off pipe, is equipped with the drain on the blow off pipe, and the through connection has the outlet pipe on the horizontal jar of body of inlet tube one side, and the intercommunication is equipped with water inlet and delivery port on inlet tube and the outlet pipe respectively, is equipped with electric control valve on the delivery port, is equipped with electric three-way valve and PLC electric cabinet.
Further, the electric three-way valve is respectively communicated with the water inlet pipe, the blow-off pipe and the external water inlet pipe.
Furthermore, the water outlet of the horizontal tank body is combined to a main water outlet pipe.
The utility model discloses an useful part: according to the size of the treated water, the number of the tank bodies is selected, the arrangement forms are various, and the installation requirements of different places are met.

Detailed Description
In order to deepen the understanding of the present invention, the following detailed description is given with reference to the accompanying drawings, which are only used for explaining the present invention and do not constitute a limitation to the protection scope of the present invention.
As shown in figure 1, the combined shallow sand filter comprises a plurality of horizontal tank bodies 1, wherein one side of each horizontal tank body 1 is provided with a visible manhole 2, the horizontal tank body 1 is communicated with a water inlet pipe 3, one side of each water inlet pipe 3 is communicated with a sewage discharge pipe 5, the sewage discharge pipe is provided with a sewage discharge outlet 51, the horizontal tank body 1 at one side of each water inlet pipe 3 is communicated with a water outlet pipe 4, the water inlet pipe 3 and the water outlet pipe 4 are respectively communicated with a water inlet 41 and a water outlet 31, the water outlet 31 is provided with an electric regulating valve 6, the horizontal tank body 1 is provided with an electric three-way valve 7 and a, the blow off pipe communicates with external inlet tube, and on the delivery port of the horizontal tank body merged a total outlet pipe, the casing was equipped with the garnet filter material, according to the grit thickness, from up the configuration down, the lower floor was thick grit, and the upper strata was thin grit, and the overall thickness of filter layer was controlled and is being controlled about 500 mm.
The PLC control box controls the action of an electric three-way reversing valve in the combined sand filter in sequence through the PLC programmable controller, so that a water inlet pipeline of a certain tank to be backwashed of the combined sand filter is closed, a sewage discharge pipeline is opened, and the tank is automatically backwashed.
The water outlets of the tanks of the combined sand filter are combined to a main water outlet pipe. When the control box sends out an instruction to carry out backwashing action on each tank body in sequence, an electric three-way valve on a certain tank to be backwashed starts to work, a water inlet is closed, a drain outlet is opened, the tank suddenly loses pressure due to the fact that the drain outlet is directly communicated with the atmosphere, a water outlet is communicated with a main water outlet pipe in a system, and therefore water reversely flows from the water outlet pipe and is discharged from a drain pipe, and backwashing on the tank is achieved. Because the water in the main water outlet pipe is the filtered water of each tank, the system does not need an additional backwashing water pump, and the energy consumption is saved.
